Solar Photovoltaic Power Converters: Technologies and Their Testing Protocols for Indian Inevitabilities

Solar Photo Voltaic (SPV) power Converter is the new emerging solar technology in the field of renewable energy. This paper discusses about the design of different technologies of commercially offered solar power converters. It highlights the information about controlling, maintenance and monitoring of various electrical parameters. Further it also discusses about the risks and challenges faced by the testing personnel while observing the performance of different technologies of SPV Power Converters. The design and operations of OFF grid and ON grid systems define the average efficiency at full load between 86% - 90% and 94% - 96.8 % respectively. Overall the system efficiency is highly dependent on the performance of charge controller and MPPT. Research and experimental results followed by testing procedure, using applicable standards for solar power converters have been obtained for the description of the efficiency percentage guiding principle.
